Omega-7: the best omega you're not getting
Everyone talks about omega-3. Almost no one mentions omega-7 — because it's rare in food. Here's what it is, why it matters, and the berry that's one of its richest plant sources.
Meet the family
There are four omegas — you've only heard about two
Omega-3
Fish, flax, walnuts
Famous · often lowOmega-6
Seed and vegetable oils
Over-consumedOmega-7
Macadamia, sea buckthorn
Rare in foodOmega-9
Olive oil (body makes it)
Non-essentialThe lay of the land
Two you balance, one you make, one you forget
Ω3
You probably need more
Anti-inflammatory and well studied — but most Western diets fall short of it.
Ω6
You probably get too much
Abundant in processed seed oils. The modern problem is the 3-to-6 ratio, not a shortage.
Ω9
Your body can make it
Non-essential — you don't strictly need it from food, though olive oil is a good source.
Ω7
The one you're missing
Genuinely rare in everyday food, which is exactly why it flies under the radar.
Why it's rare
Hardly any food carries meaningful omega-7
worth naming
Macadamia nuts and sea buckthorn — that's about it
Unlike omega-3 or 6, omega-7 (palmitoleic acid) shows up in very few foods at a level that matters. Macadamia nuts are one. Sea buckthorn is the other — and it's one of the richest plant sources known.12
What it's studied for
Where the research is looking
Skin and barrier
Palmitoleic acid is a natural component of skin lipids; sea buckthorn has been studied for skin and mucosal-barrier support.
Metabolic markers
Early research has examined palmitoleic acid's role in lipid and metabolic signalling — promising, but still developing.
Mucous membranes
Traditional and modern use has focused on moisture and comfort of the body's mucosal tissues.
To be clear: omega-7 is an area of active research, not settled medicine. These are directions science is exploring — not promises. Sea buckthorn supports these systems as a nutrient-dense food.3
The richest plant source
Why sea buckthorn is the omega-7 berry
Most "omega" supplements give you 3, 6 or 9. Sea buckthorn is unusual because it delivers all four — including the rare omega-7 — in a single whole fruit, alongside its vitamin C, vitamin E and carotenoids.12
The honest take
What omega-7 is — and isn't
Omega-7 won't replace omega-3, and it isn't a cure for anything. What makes it interesting is its rarity: it's a fatty acid most people simply never encounter in food, so getting any meaningful amount usually means a deliberate source.
That's the real case for sea buckthorn. Not "miracle berry" — just one of the only everyday foods that puts the full omega spread, omega-7 included, on your plate at once.
Get the full spread
All four omegas, one wild berry
A cold-pressed sea buckthorn purée keeps the fruit's natural oils — and the omega-7 with them — intact, where heat-processed powders and watered-down juices lose them.

One wild berry, cold-pressed into single-serve pouches — the rare omega-7 plus vitamin C, vitamin E and antioxidants, oils intact. 60 pouches = a 2-month supply, free shipping to Canada and the US, 60-day guarantee.

Common questions
What is omega-7?
Omega-7 is a monounsaturated fatty acid — most commonly palmitoleic acid. It's far less common in food than omega-3, 6 or 9.1
What foods contain omega-7?
Very few. Macadamia nuts and sea buckthorn are the two everyday sources worth naming; sea buckthorn is among the richest plant sources.2
Is omega-7 better than omega-3?
It's not "better" — it's different and rarer. Omega-3 is essential and well studied; omega-7 is harder to get from food, which is what makes a dedicated source useful.1
Does sea buckthorn have all the omegas?
Yes — it's one of the few foods supplying omega-3, 6, 7 and 9 together in a single fruit.2
